Definitions

  • FIG. 7 is a top plan view of a sanitary napkin with portions cut way to more clearly show the construction of the sanitary napkin;
  • FIG. 8 is a cross-sectional view of the sanitary napkin of FIG. 7 taken along line 8- 8;
  • FIG. 9 is a simplified schematic illustration showing an apparatus for forming a web of the present invention.
  • Such macroscopically-expanded webs, ribbons and films are typically caused to conform to the surface of the forming structures by embossing (i.e., when the forming structure exhibits a pattern comprised primarily of male projections), by debossing (i.e., when the forming structure exhibits a pattern comprised primarily of female capillary networks), or by extrusion of a resinous melt onto the surface of a forming structure of either type.
  • planar when utilized herein to describe plastic webs, ribbons and films, refers to the overall general condition of the web, ribbon or film when viewed by the naked eye on a macroscopic scale.
  • planar a non-apertured extruded film or an apertured extruded film that does not exhibit significant macroscopic deformation out of the plane of the film would generally be described as planar.
  • rigid materials include any material having an elastic modulus of at least 120 kpsi.
  • substantially less rigid materials include materials having an elastic modulus of not greater than 75 kpsi.
  • Elastic moduli of materials may be determined by reference to data in published materials such as "Material Science of Polymers for Engineers" by T.A. Oswald and G. Menges, published in 1996 by Hanser Publishers, New York, NY. Elastic moduli may also be determined directly by testing, such as by the method set forth in ASTM D638.
  • FIG. 3 shows an enlarged partially segmented, perspective illustration of a microapertured, macroscopically-expanded, three-dimensional, compression resistant web embodiment of the present invention, generally indicated as 80.
  • the geometrical configuration of the fluid-pervious, compression resistant web 80 is generally similar to that of prior art web 40, illustrated in FIG. 1, and is generally in accordance with the teachings of the aforementioned '314 Radel et al. and "643 Curro et al. patents.
  • Other suitable formed film patterns and configurations are described in commonly-assigned, copending, U.S. Pat. Application Serial No. 08/816,106, filed March 14, 1997; U.S. Pat. No. 3,929,135, issued to Thompson on Dec. 30, 1975; U.S.
  • each interconnecting member comprises a base portion, e.g., base portion 81, located in plane 102, and each base portion has a sidewall portion, e.g., sidewall portions 83, attached to each edge thereof.
  • the sidewall portions 83 extend generally in the direction of the second surface 85 of the web and intersect with side walls of adjoining interconnecting members.
  • the intersecting sidewall portions are interconnected to one another intermediate the first and second surfaces of the web, and terminate substantially concurrently with one another to form a secondary aperture, e.g., secondary apertures 72 in the plane 106 of the second surface 85.
  • Microapertures 225 are formed on the film prior to macroscopically expanding the film to form a substantially uniform distribution of surface aberrations 220 on the macroscopically expanded web.
  • Microapertures 225 can be formed by a hydroformation process at points which coincide substantially with the maximum amplitude of each surface aberration 220. As can be seen in FIG. 2, rupturing of the surface aberrations 220 at these points results in the formation of a volcano-shaped aperture 225 having relatively thin, irregularly shaped petals 226 about its periphery.
  • a particularly preferred multilayer polymeric film 120 capable of being formed into a web 80 of the present invention is depicted in cross-section in FIG. 5.
  • rigid layer 103 can be coextruded together with a substantially less rigid layer 101.
  • the thickness (caliper) of rigid layer 103 is from about 5% up to about 40% the total film thickness.
  • the thickness of the rigid layer 103 is from about 5% to about 20% of the total film thickness.
  • the thickness of the rigid layer is approximately 10% or less of the total film thickness, and may be termed a "skin layer".
  • the rigid layer 103 can comprise polypropylene having an elastic modulus of from about 155 kpsi, up to about 290 kpsi. In another embodiment the rigid layer can comprise polystyrene (having an elastic modulus from about 350 kpsi, up to about to 460 kpsi), particularly if blended with other thermoplastic materials. In one embodiment, the rigid layer 103 is a 70/30 blend of polypropylene/polystyrene (i.e., 70% polypropylene, 30% polystyrene), having a modulus intermediate to that of either polypropylene and polystyrene.
  • the substantially less rigid layer 101 comprises a material having an elastic modulus not greater than about 75 kpsi.
  • Suitable materials for the substantially less rigid layer include polyethylene (including low density polyethylene and linear low density polyethylene) having elastic moduli as low as about 28 kpsi, and ethylene vinyl acetate (EVA), having an elastic moduli less than about 25 kpsi and generally greater than 3 kpsi.
  • Other materials suitable for use as the substantially less rigid layer 101 include metallocene polyethylene with densities between about 0.90 and 0.93 g/cc, ethylene acrylate copolymers such as methyl acrylate, and ethylene propylene copolymers such as Adflex® sold by Montell Polyolefins in Wilmington, DE.
  • a preferred method to produce the multilayer polymeric film 120 is coextrusion, as discussed in detail below.
  • the rigid layer should have sufficient adhesion to the substantially less rigid layer such that it will not delaminate either before, during, or after further processing.
  • Dissimilar materials such as polystyrene and polyethylene, when coextruded, may not exhibit good adhesion to one another, so an adhesive layer may be needed to provide adequate adhesion for sufficient film integrity.
  • an adhesive layer may be needed to provide adequate adhesion for sufficient film integrity.
  • equate adhesion is meant that the two (or more) layers are joined sufficiently so as to not delaminate during further processing.
  • the layers may be joined substantially continuously over the entire layer, or they may be bonded at discrete, discontinuous areas such as a uniform pattern of closely-spaced spot bonds.
  • thermoplastic materials even dissimilar materials, may be blended and used in the rigid layer, provided that at least one of the materials exhibits adequate adhesion to the substantially less rigid layer, and it is present in sufficient quantity at the material interface to provide adequate adhesion.
  • the primary advantage to blending materials in the rigid layer is that the modulus can be increased by blending higher modulus, but non-adhering, components with lower modulus, but adhering, components. By using a greater quantity of adhering components adequate film integrity can be obtained.
  • the interconnecting elements are inherently continuous, with contiguous interconnecting elements blending into one another in mutually-adjoining transition zones or portions, e.g., transition portions 87.
  • transition portions are defined by the largest circle that can be inscribed tangent to any three adjacent apertures. It is understood that for certain patterns of apertures the inscribed circle of the transition portions may be tangent to more than three adjacent apertures.
  • interconnecting members may be thought of as beginning or ending substantially at the centers of the transition portions, such as interconnecting members 97 and 98.
  • the sidewalls of the interconnecting members can be described as interconnecting to sidewalls of contiguous interconnecting members.
  • the sanitary napkin 20 has two centerlines, a longitudinal centerline '1" and a transverse centerline “t".
  • transverse or “lateral” as used herein, are interchangeable, and refer to a line, axis or direction which lies within the plane of the sanitary napkin 20 that is generally perpendicular to the longitudinal direction.
  • Sanitary napkin 20 preferably includes optional side flaps or "wings" 34 that are folded around the crotch portion of the wearer's panties.
  • the side flaps 34 can serve a number f purposes, including, but not limited to protecting the wearer's panties from soiling and keeping the sanitary napkin secured to the wearer's panties.
  • the multilayer film 120 of the present invention may be processed using conventional procedures for producing multilayer films on conventional coextruded filmmaking equipment.
  • polymers can be melt processed into films using either cast or blown film extrusion methods both of which are described in Plastics Extrusion Technology-2nd Ed., by Allan A. Griff (Van Nostrand Reinhold-1976), which is hereby incorporated herein by reference.
  • Cast film is extruded through a linear slot die.
  • the flat web is cooled on a large moving polished metal roll. It quickly cools, and peels off the first roll, passes over one or more auxiliary rolls, then through a set of rubber-coated pull or "haul-off rolls, and finally to a winder.
  • blown film extrusion the melt is extruded upward through a thin annular die opening.
  • This process is also referred to as tubular film extrusion.
  • Air is introduced through the center of the die to inflate the tube and causes it to expand.
  • a moving bubble is thus formed which is held at constant size by simultaneous control of internal air pressure, extrusion rate, and haul-off speed.
  • the tube of film is cooled by air blown through one or more chill rings surrounding the tube.
  • the tube is next collapsed by drawing it into a flattened frame through a pair of pull rolls and into a winder.

Le voile comprend une première surface, qui présente une pluralité de micro-orifices constituant des aberrations de surface en forme de volcans, et une seconde surface, qui est généralement parallèle et décalée par rapport à la première surface. Une pluralité de passages d'écoulement fluidique s'étendent entre la première et la seconde surface de façon à les mettre en communication fluidique. Le voile est formé d'un film polymère multicouche, comprenant au moins une couche rigide et au moins une couche sensiblement moins rigide réunie à la couche rigide. Dans un mode de réalisation préféré, une couche rigide a un module d'élasticité d'au moins 120 kpsi et une couche sensiblement moins rigide un module d'élasticité inférieur ou égal à 75 kpsi. Le film multicouche est de préférence formé par coextrusion d'une couche rigide, comprenant un mélange de polystyrène et de polypropylène, et d'une couche sensiblement moins rigide, comprenant un mélange de polyéthylène basse densité et de polyéthylène basse densité linéaire.
